One of those episodes that sets up an apparently unearthly/monstrous threat before deconstructing it. The opening is rather reminiscent of an Auton attack, with a blank-faced figure menacingly advancing with outstretched gun-hand. But we find it's purely human researchers who are behind him and his power to create massive electrical discharges.
A choice of possible villains in this one, something we don't always get in The Avengers. Surely it must be bitter Peter Blythe from A Sense of History, not harmless Ray McAnally!
One of my favourite supporting characters so far in ultra-professional nerdish secretary Miss Wentworth-Howe (Caroline Blakiston making her third appearance). The reaction from Mrs Peel to her producing the safe key from her stocking top is delightful, as is the revelation that she spends her days orf fly-fishing. She doesn't need any tips from Steed either.
Some enjoyable disdain from Mrs Peel when exposed to the sight of a naked man liberally smeared with non-conducting oil.
Nice to see some attempt at justification, on experimental grounds, for the unnecessarily complex way that the villains choose to try and finish off our heroes.
